I am using Firebase Cloud functions priced plan (!) for a webhook for google actions. I am trying to implement a HTTP GET with the request-module. I have installed the module with npm install request and deployed correctly. I want to use google maps distance-matrix api.

For some reasons I am not able to use the request module at all. In the log I neither see "ERROR in GET" nor "being SUCCESSFULL". Any idea what the issue might be?

// Handle the Dialogflow intent named 'Default Welcome Intent'.

app.intent('Default Welcome Intent', (conv) => {



  var url = "https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=Washington,DC&destinations=New+York+City,NY&key=AIzaSyBich-7OBAxvtAwX5XnHQyJ7xZiJ8libVQ";



  request({url: url, json: true}, (err, resp, body) => {

    if (err) {

      console.log('ERROR in GET');

      conv.ask('ERROR in GET');

    }

    else { 

      conv.ask('beeing SUCCESSFULL');

      console.log('beeing SUCCESSFULL');

    }

  })

Thank you in advance and best regards.

Here when you are doing async work inside handler function , you have to return a Promise that does that work , because otherwise there would be empty response and error. so

app.intent('Default Welcome Intent', (conv) => {

     return Promise(function(resolve,reject){

          request({url: url, json: true}, (err, resp, body) => {

               if (err) {

                  console.log('ERROR in GET');

                  conv.ask('ERROR in GET');

               }else { 

                  conv.ask('beeing SUCCESSFULL');

                  console.log('beeing SUCCESSFULL');

               }

               resolve()

          })   

     })

})

Hope this works for you.

I think found a solution. Apparently it seems to be not possible to use conv.ask() within a promise for some reason. It is necessary to pass an argument. The following code does work:

const p = new Promise(function(resolve,reject){

          request({url: 'YOUR_URL', 

                   json: true}, (err, resp, body) => {

               if (err) {

                  // do not use conv.ask() here

                  resolve('no ok');

               } else { 

                  // do not use conv.ask() here

                  resolve('ok');

               }



          }) 

})



app.intent('Default Welcome Intent', (conv) => {



    p.then(resp => conv.ask('resp'));

    conv.ask('foobar');



})
